EIILSWORTII W. AUSTIN, OF PLYMOUTH, CONNECTICUT.

VAPOBIZING-STOPPER.

Application filed June 2,

T 0 all whom it may concern:

Be it known that I, ELLSWORTH W. AUS- TIN, a citizen of the United States, and a resident of Plymouth, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Vaporizing-Stoppers, of which the following is a specification.

This invention relates to improvements in devices of that class available for enhancing the vaporization of the power medium or fluid, inflowing to the interior of the cylinder or cylinders of an explosive engine, and essentially to facilitate the starting thereof, and more particularly to vaporizing stoppers of that type wherein electric current is employed for heating.

The objects of this invention are to provide a stopper which shall be simple and inexpensive as regards its construction; convenient in its application to practical purposes, durable, efficient and reliable in service; and which shall possess certain well de fined advantages over prior analogous constructions.

I attain the foregoing objects by means of the construction shown in the accompanying drawing, in which:

Figure 1 is a side elevation of a vaporizing stopper embodying my said improvements, in use.

Fig. 2 is a top plan view of the improvement, the heated portion of which is shown in central horizontal section, as along the broken line w-m of Fig. 1.

Fig. 3 is a detail view in side elevation of the tapering shell shown detached, which I purpose making use of.

Fig. 4 is an end view of the same.

In a general sense my improved stopper comprises an elongated shell housing an electrically heated element, said shell provided with means for conveniently handling the same, and adapted to be used substantially as explained in my co-pending application filed February 28th, 1919, Serial Number 2798M.

Having reference to the accompanying drawing, wherein similar reference numerals denote like parts throughout the several views, I, in carrying out my invention, make use of a hollow stopper shell 6' a novel part of stopper 6, to be heated from within by heating element 10, the cylindrical wall 6 of said stopper shell tapering inwardly along a considerable portion of its length Specification of Letters Patent.

Patented Apr. 20, 19.20.

Serial No. 301,333.

and terminating at the closed end 6 best shown in Fig. 2.

Any appropriate handle may be made use of for inserting stopper 6 into stopper-receiving opening 2 of joint-block 2 and removing said stopper therefrom, though in this connection I contemplate providing a hollow tube 9 terminating in a suitable insulated plug 9 and projecting from flange 9", said flange providing at its rim a means whereby the open end of stopper shell 6 may be fused to it.

The aforenamed heating element 10 may consist of a plurality of suitable insulated resistance coils 10 and be arranged to receive current through insulated conductors 10 which lead into said heating element through the above described handle.

The function of the aforesaid heating element which is preferably of a type now in general use; is to transform to heat, the electrical energy received.

The operation of the improved stopper may be briefly described as follows: Referring to the above mentioned application for patent, wherewith the stopper to be preheated is replaced by the improved stopper, and the stopper receiving opening 2 is effectively closed. The power mixture in traversing the passage 2 is vaporized to a greater extent by coming in contact with. the heated surface of the improved stopper which in turn is constantly being heated from within by the resistance to the electrical current passing through the heating element 10.

It will be seen that my improved stopper is well adapted for the purposes for which it is intended, and further, that the same may be modified to some extent without material departure from the scope of the claims hereto appended.

I claim:

1. A device of the class herein described comprising a stopper shell having a tapered exterior for displaceably closing the stopper-- receiving opening of a -joint-block, and housing an electrical heating element.

2. A. device of the class herein described comprising a stopper shell having a tapered (XLQL'lQl' for displaceably closing the stopper receiving opening of a joint-block, and housing an electrical heating element, and a handle suitably arranged to facilitate the operation thereof.

3. A device of the class herein described placeably comprising a stopper shell housing an electrical heating element and arranged for disclosing the stopper-receiving opening of a joint-block to vaporize to a greater extent the power-mixtureof an explosive engine.

4:. A device of the class herein described comprising a stopper shell having a tapered exterior for displaceably closing the stop perreceiving opening of a joint-block, and housing an electrical heating element, and a handle suitably arranged to convey conductors leading to-said heating element, and to facilitate the operation of the device.
